Life Drain 2014
3rd-level necromancy
You send tendrils of necrotic energy out, sucking the life essence from your foes. Select up to three creatures within range that aren’t constructs or undead. Make a ranged spell attack against each target, dealing 3d6 necrotic damage on a hit. You regain hit points equal to half the damage dealt.
At higher levels
When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 for every two slot levels above 5th.
